3 feet tall...sturdy as all get out for the bottom four levels, but the top one is a bit wobbly. It's four separate pieces; both doorways, the tower, and the back wall. I've played with the idea of someday building a "throne room" top to the tower--that would lend it some more stability, I think. And since I'll have to refurbish some of these pieces anyway...

I was actually having a lot of fun the other day (during the photo shoot) by just kind of throwing the rooms and levels together in different combinations...perhaps I can do more updates in the future with some different setups.
